TO ALL WHOM IT MAY CONCERN;

Be it known that I, R. W. BIGGS, of Jacksonville, inthe county of.Duval, and State of Florida, have invented a new and useful improvementin Plouglls; and I do hereby declare the following-t0 be a full andexact description thereof, reference being had to the accompanyingdrawings, forming a part-of this specification, in which- Figure 1 is aside elevation of my improved plough; and

Figure 2, a'perspective view of the slotted stock and itsadjusting-plate.

Similar letters indicate like parts in each of the figures.

The nature of my invention consists in the combination of a slottedstock, pivoted to a suitable beam, with a point or share and astationary semicircular adjusting-plate in the construction of a plough.

In theaccompanying drawing, A represents the beam of a ploughconstructed after any approved pattern, and provided with handles B,secured thereto in any suitable manner. To this-beam I pivot a slottedstock, (1-, by means of a bolt and nut, a, fig. 2, in such manner asthat the slot 8 shall be parallel with the beam. The lower end of thestock is so curved forward as to receive and support closely theploughshare or point to be secured thereto; and the share or point issecured to this lower end of the stock byv means of a bolt passingtlirough the slot- 8, and fastened by a nut: This mode of fasteningadmits of'a vertical adjustment oftheshare or point uponthe stock, thisadjustment-serving, by means of the curve of the lower end'of saidstock, to determine the inclination at which the point shall enter thesoil, and the pitch at which it shall work. As the curve of both stockand point are made to coincide, the support of the point is equallyelosc in all its adjustments. The movement or play of the stock upon itspivoted connection to the beam A allows 'anadjustment thereof to anydesired inclination, it being secured, when so adjusted, by means of asemicircular plate or bar, D, which passes through the upper end of theslot 8 in the stock, and is secured at either end to the beam of theplough. This plate D is pierced with holes at regular intervals, toreceive a bolt, 0, passing through an aperture in the stock, piercedtransversely across its slot, the bolt being secured, after it has beenthus inserted through the stock and plate to hold the former, by meansof a nut screwing thereon. This adjusting-plate not only allows of anadjustment of the stock to set its point for deeper shallow Work, butserves also as an effective brace therefor.

Having thus fully described my invention, I do not claim the use of aslotted stock admitting of a vertical adjustment of the point or share;nor do I claim pivoting the stock to admit of an adjustment of itsinclination; but whatI do claim thereih as ne w, and desire to secure byLetters Patent, is

The combination and arrangement of the slotted stock 0, point or shareE, and semicircular stationary adjusting-plate D, with each other andwith a suitable plough-beam A, substantially inthe manner and for thepurpose herein set forth.

The foregoing specification of my improvements in plonghs signed by methis day of A. D. 1867.
